Fulfill Git Escrow

You are helping the user fulfill a git escrow bounty. This means submitting code that passes a failing test suite to claim the escrowed token reward.

There are two modes:

• Mode A (Write + Submit): You write the solution code, commit it, and submit. This is the default when no --solution-repo is provided by the user.
• Mode B (Submit Existing): The user already has a solution repo and commit. You just submit the fulfillment.

Determine the mode from the user's input:

• If they provide --solution-repo, use Mode B.
• Otherwise, use Mode A.

The escrow UID is always required.

Step 1: Check CLI availability

Run git-escrows --help to verify the CLI is installed. If it fails, try npx git-escrows --help or bunx git-escrows --help. Use whichever works for all subsequent commands. If none work, tell the user to install with npm i -g git-escrows.

Step 2: Check .env configuration

Check if a .env file exists in the current directory. If not, tell the user they need one and suggest running:

git-escrows new-client --privateKey "0x..." --network "sepolia"

Step 3: Validate the escrow

Run git-escrows list --verbose --format json and find the escrow matching the provided UID. Confirm:

• The escrow exists and is open
• Note the test repo URL, test commit hash, reward amount, and oracle address

If no escrow UID was provided, ask the user for one. You can help them browse with git-escrows list --status open.

Mode A: Write Solution + Submit

A1: Understand the tests

Clone or read the test repository to understand what the tests expect:

1. Identify the test repo URL and commit from the escrow details
2. Clone it to a temporary location: git clone <url> /tmp/escrow-tests-<uid> && cd /tmp/escrow-tests-<uid> && git checkout <commit>
3. Read the test files to understand:
   • What functions/modules/APIs the tests import
   • What behavior they assert
   • What test framework is used
   • The project structure expected

A2: Write the solution

In the current working directory (or a subdirectory the user specifies):

1. Create/modify files to implement the code that will make the tests pass
2. Follow the project structure the tests expect (e.g., if tests import from src/math.ts, create that file)
3. Include any necessary config files (package.json, Cargo.toml, etc.)
4. Ensure the test framework's dependencies are accounted for

A3: Commit and get repo details

1. Stage and commit the solution: git add -A && git commit -m "solution for escrow <uid>"
2. Get the commit hash: git rev-parse HEAD
3. Get the remote URL: git remote get-url origin
   • If no remote exists, ask the user to push to a public git repo and provide the URL

A4: Submit the fulfillment

git-escrows fulfill \
  --escrow-uid "<uid>" \
  --solution-repo "<repo-url>" \
  --solution-commit "<commit-hash>"

Mode B: Submit Existing Solution

B1: Gather parameters

From the user's input, extract:

• --solution-repo: The git repo URL with the solution
• --solution-commit: The commit hash of the solution

If either is missing, ask the user.

B2: Submit the fulfillment

git-escrows fulfill \
  --escrow-uid "<uid>" \
  --solution-repo "<repo-url>" \
  --solution-commit "<commit-hash>"

Step 4: Report results (both modes)

After successful execution:

• Report the Fulfillment UID prominently
• Explain that the oracle will now automatically test the solution
• Provide the collect command for after arbitration passes:

  git-escrows collect --escrow-uid <escrow-uid> --fulfillment-uid <fulfillment-uid>
  

• Suggest checking status with: git-escrows list --verbose

If the command fails, help diagnose the issue (escrow already fulfilled, wrong network, key not registered, etc.). If the user's git key isn't registered, suggest git-escrows register-key.
